Wet-separation type dust collector for vacuum

Abstract

The present invention relates to a wet-separation type dust collector for a vacuum cleaner. Said dust collector comprises: a dust collecting unit for collecting dust discharged from a centrifuging unit, and a water storage unit for producing liquid drops to be sprayed into said dust collecting unit, and said dust collecting unit has a plurality of spraying holes for spraying liquid drops by means of a vacuum pressure created in the inner side of the vacuum cleaner. By the above configuration, the dust collector of the present invention can effectively separate dust particles from the centrifuging unit by evenly spraying liquid drops into the entire interior of the dust container. In addition, the dust collector prevents the backflow of floating dust particles in the dust container by rapidly transferring the dust particles towards the lower side of the dust container.

The invention claimed is: 
     
       1. A dust collector for a vacuum cleaner comprising:
 a dust collecting unit to collect dust particles discharged from a centrifuging unit; and 
 a water storage unit to store water, 
 wherein the dust collecting unit is formed at a side wall thereof with a plurality of liquid droplet spray holes so that liquid droplets are automatically sprayed into the dust collecting unit by vacuum pressure of the vacuum cleaner, and 
 wherein the water storage unit is coupled to an outer side surface of the dust collecting unit so as to form a water storage region at an outer side of the dust collecting unit. 
 
     
     
       2. The dust collector according to  claim 1 , wherein each of the plural liquid droplet spray holes has a different diameter. 
     
     
       3. The dust collector according to  claim 1 , wherein each of the liquid droplet spray holes has a diameter of 0.3 mm to 10 mm. 
     
     
       4. The dust collector according to  claim 1 , wherein the water storage unit has a smaller volume than the volume of the dust collecting unit. 
     
     
       5. The dust collector according to  claim 1 , wherein the water storage unit further comprises a handle portion which has a water inlet opened at an upper portion thereof and is formed at a base portion thereof with a through hole to communicate with a water storage region of the water storage unit. 
     
     
       6. The dust collector according to  claim 1 , further comprising:
 water supply portions located in the water storage unit while being respectively formed at positions of the liquid droplet spray holes. 
 
     
     
       7. The dust collector according to  claim 6 , wherein each of the water supply portions is formed at a base portion thereof to be submerged under the water stored in the water storage unit. 
     
     
       8. The dust collector according to  claim 6 , wherein each of the water supply portions is formed to have an inner diameter greater than a diameter of each liquid droplet spray hole. 
     
     
       9. The dust collector according to  claim 6 , wherein each of the water supply portions is vertically provided at an outer peripheral surface of the side wall of the dust collecting unit.
